tions, and arrangements, hereinafter de-- g5 scribed and claimed.

An object of my invention is to provide a device of the type describedwhich may be readily attached to a receiving set without the necessityof altering the construction of 510 the latter.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims. y

My invention is illustrated in the accompanying drawings, forming a partof this application, in which- Figure 1 is a View showing the deviceoperatively connected to a receiving set, and

Figure 2 is a wiring diagram of the device.

In carrying out my invention, I provide containers 1 and 2 eachcontaining a brine solution 3 and 4 respectively. A wire 5 leads 125from the brine 3 to an aerial 6. A second wire 7 leads from the brine 3to one terminal of a battery 8.

From the other terminal of the battery 8, a wire 9 leads to the brine 4in the container 30 2. The radio frequency current flowing from 13 andare connected to a common wire 18 second container having asolutionofbrine therein, electrical .ccndu'ctors" for coriencting at 19. Thewire 18, iny turn, is connected to the antenna binding post 20 of thereceiving set 21. The receiving set 21 may be of any vstandard make andhas its usual ground terminal 22 connected to the ground 23 by means ofa wire 24.

Freni the foregoing description of the These bars are connected variousparts'ofthe device, the'opcration thereof may be readily understood. Itwill be vnoted that the circuit vfor .the incoming signals is providedby meansof'the aerial,

Wire 5, brine-3,fwir,e 7 battery 8, wire9, brine 4, rods .12*and'13,wires 16 and17, and wire 21,8. I have foundjout, yfrom practice, thatthe Vbrine solutions 3` and4, together with the battery 8, andthetherinocouple, actually eliminatesallgstatic and permits `only signalsofV a desired frequency` to pass kthru `the circuit undisturbed. i

, Alocal current is generated in the wires 16 'and 17 and the rodsf12and 13,' duetothe fact Ithat the `rods 12 and {13.ha-ve .their lowerends .disposed in the relatively cool `brine solutions l.while theirupper ends are,.of course, of Aa warmer temperature. .The theory ofthethermocouple would applyin thiscase'a'nd cau'sethe local current to'flow thru-the; wires 16.and17 andthe rods 12 and13 as aforesaid.
